What is a utility stair

Landings in a stair is a level floor or platform constructed at a location where the direction of stairs changes, between flights of the stair, or at the top of stair flight.With utility stairs, a maximum of 16 steps is allowed before a landing.Your stair tread can be greater than 220mm (going), and the step height can be below 220mm (rise) provided that twice the rise plus the going (2r+g) falls between 550mm and 700mm.Approved document k does not give guidance on the width of a 'general access stair', only for rise and going (see table 1.1).Doors opening onto a landing cannot reduce the minimum landing width to.

Landings (ibc 1011.6 & 1009.6.3) there must be a floor or landing at the top and bottom of each stairway.Starting with means of egress stairways, ibc defines means of egress as a continuous and unobstructed path of vertical and horizontal egress travel from any occupied portion of a building or structure to a public way.Where the stairway has a straight run, the landing does not need to be more than 48 inches deep.The maximum number of risers between landings should be 16 for utility stairs and 12 for general access stairs.A stair, or a stairstep, is one step in a flight of stairs.

This is because open risers have many functional and stylistic benefits that closed risers lack.Osha stairs are required to be a minimum of 22 inches wide.The exit access, the exit, and the exit discharge.
